I do know if this is considered an injury, but its definately a problem.
I'm pretty new to jelqing, and I have gotten some modest gains in length and girth. But my problem is this: when I get hard, the lower portion of the shaft doesnt fill out with the rest of my penis, it stays flaccid while the rest gets firm. By the time I am "fully" erect the lower portion finally gets hard, but it is still skinnier than the rest. I put "fully" in quotes because my erections have been weaker than normal and I am worried that I have done something to damage the blood flow through the lower portion of my penis. I am not sure if the weaker erections are directly related to the jelqing, or if it is just a coincidence. Please tell me if you have any idea how to fix this problem. Thanks
